Which isn't-exactly laziness!EDIT: So -for me- I do not see principle differences between zooms and primes - except if f/2 at 100mm can only realized with aprime or in the case of real macro.One hint to Canon and other manufacturers: give us a click-option for focal length stops e.g. 24-35-50 -85-105 and a focal length hint in the viewfinder! ??
